I planted Hibiscus seeds outdoors in the Spring ….
They are just about one foot tall now. I would like to transplant a few to pots for over winter, as we get below freezing most of the winter. Advise how best to take care.

If you are bringing in a potted tropical hibiscus, you can hose it down well with water and cut it back by up to 1/3 before bringing it indoors. Neem oil is a good treatment for any pest issues that you may have. If your plant is a hardy variety, it will not require any special care over winter and should not be cut back until spring.
